This invention relates to the D'litliillg of motor cylinders andparticularly to the forniing'of C Vllfltl'rl' blocks :LIHl torunner-tin; various parts of builtiip cylinders.

One of the objects of the invention is to connect metal purts h v z:novel method or process.

Another olijert of the invention i.\ to biiiltl up a motor cylinder byit novol method.

this ring" it; is c-pw elto thou-tit r t elbow and its ring 46 areinserted through the opening ll so that the jacket rests against thebase of the ring 46 and the shoulder d7 formed by the extended partofthe flange 45. Awelding heat is now applied to the ring 46 and theadjacent part of the jacket 22 so that these metal parts flow togetherand form a Welded joint. This oint is iiidicated in dotted lines at48.Similar joints are made at {9 and 50 as shown in Fig. .1.

It will be understood that modifications may be made in. the abovedescribed method- Without departing from the spirit or scope of theinvention.

Having thus described my invention, what I claim and desire to secure byLetters Patent is 1. A method of welding .a piece of sheet metal havingan opening therethrough to a piece of metal adapted to extend throughand practically fill. said opening, consisting in forming the innerpiece with an external flange and with a ring on said flange arrangedparallel with and separated from the outer wall of the piece with theflange ex-' tending beyond the ring to form a. shoulder then insertingsaid inner piece through said opening with the sheet metal against saidshoulder and surrounding said ring, and then, while the surface of thesheet metal next adjacent is exposed, heating said ring and the adjacentsheet metal piece and etfecting a weld between them.

2. A method of: welding a piece of sheet metal to a tube consisting informing the tube with an external circumferential flange and with a ringon the flange separated fromand parallel to the outer wall of the tubeleaving part of the flangeextending beyond I part of the flangeextending beyond the ring to form a shoulder, cutting a hole in thesheet metal and fitting it over said ring and against said shoulder, andheating said ring forming the thicker piece with a flange extendinglaterally from its wall and with a rim on said flange arranged parallelwith and separated from the wall of the piece with the flange extendingbeyond the rim to form a shoulder, then placing the thinner piece normalto the wall of the thicker piece and against said shoulder and withitsedge against the outer surface of said rim, and then, while part ofthe outer surface of said rim and the surface of the thinner piece nextadjacent thereto are both exposed, heating said rim and adjacent partsof the thinner piece and'eflecting a weld between them.

A method of uniting two pieces of metal of different thicknessesconsisting in forming the thicker .piece with a flange extendinglaterally from its wall and with a rim on said flange arranged parallelwith and separated from the wall of the piece with the'flange extendingbeyond the rim to form a shoulder, then placing the thinner piecenormalto the wall of the thicker piece and against said shoulder andwith its edge against the outer surface of said rim, and then, while theedge of said riin'and the surface of the thinner piece next adjacent tothe rim are both exposed, heating said rim and adjacent parts of thethinner piece andei'fecting a weld between them.

(5. A method of welding a plece of sheet metal to atube consisting informing the tube with an external flangeand with a ring on the flangeseparated hem and parallel tothe outer wall of the tube leaving part ofthe flange extending beyond the ring to form a shoulder, the ring andthe part of the flange extending beyond it being of suhstantially thethickness of the sheet metal, fitting I said sheet metal over said ringand against said shoulder, and heating the adjacent parts of the flangeand sheet metal to cause them to flow together.

In testimony whereof I aflix my signature.
